Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like fatigue, weakness, or neurological issues that could be linked to copper imbalance. It may also be used to monitor conditions like Wilson’s disease (a genetic disorder affecting copper metabolism) or to check for copper toxicity.

What to Expect Before the Test

No special preparation is usually needed. You may fast for 8–12 hours before the test if instructed, but always follow your provider’s guidance. Bring any medications or supplements you’re taking, as they can sometimes affect results.

How the Test Is Performed

A blood sample is drawn from a vein, typically in your arm. The blood is then sent to a lab for analysis to measure copper concentration.

What the Results Mean

Results are compared to a reference range, but exact values can vary by lab. Low copper levels may indicate deficiencies, while high levels could signal conditions like Wilson’s disease or liver problems. Your provider will interpret results in the context of your overall health.
